Here you can find organizations, locations, tutorials, seminars etc.,
that I can recommend without hesitation:

SMil Danmark(Denmark): A danish BDSM organization, based in Copenhagen, Aarhus, Odense and Aalborg.

Locations and places:

SMart Café (Vienna/Austria): The SMart Café is a BDSM themed café/bar/restaurant, where the local kinksters love to hang out. There is a small play area in the back. Food and drinks are good as well.
